This is a pair of aftermarket replacement remotes. One remote is brand new and one was used for just a few months. These are super small and easy to carry. Better yet / super easy to program (and usually these things are a huge pain to program- this one is simple!). In fact, I guarantee that they will work with the models below. If they don’t work, you can bring them back to me within 48 hours for a refund. I still have original box. I have a 15 year old Genie and these remotes work for that model as well as for the following model numbers: ACSCTG Type 1, ACSCTG Type 2, ACSCTG Type 3. ACSGT Type 1, ACSGT Type 2, ACSGT Type 3.
